| Diameter tolerance± mm | Not documented | ±0.04 (Prusament PC Blend Carbon Fiber)[3] |
| Printing Parameters | ||
| Nozzle temperature°C | 240–270 (Bambu Lab); 245–265 (Polymaker PolyLite)[5][1] | 285 ± 10 (Prusament)[3] |
| Bed temperature°C | 80–100 (Bambu Lab); 90–100 (Polymaker)[5][1] | 110 ± 10 (Prusament)[3] |
| Enclosure / chamber requirement1–5 | Enclosure recommended — Polymaker calls a chamber needed at ambient temperature, Bambu Lab requires an enclosed printer and rules out its P1P and A-series machines[1][22] | Enclosure required (passive)[3][22] |
| Recommended chamber temperature°C | 45–60 (Bambu Lab)[5] | Not documented |
| Part cooling fan | 0–80 % (Bambu Lab); off (Polymaker PolyLite)[5][1] | Off — Prusa allows 0–20 % and warns cooling significantly reduces interlayer adhesion[3] |
| Bed surface & adhesion aid | Clean the plate and apply glue — Bambu Lab lists glue as the way to improve adhesion and prevent warping[22] | PEI with a glue stick or a commercial adhesive[23] |
| Maximum volumetric flow (mm³/s; see test conditions)mm³/s | 10–16 (PrusaSlicer guidance for ABS/ASA)[24] | Not documented |
| Warping tendency1–5 | High — enclosure needed for reliable large parts; Bambu Lab attributes surface cracking to cooling stress exceeding interlayer adhesion[22] | High — enclosure needed for reliable large parts; the fibre reduces warping against unfilled PC[3][22] |
| Bed-adhesion difficulty1–5 | Needs a specific surface plus adhesive[22] | Needs a specific surface plus adhesive[23][25] |
| Stringing / oozing tendency1–5 | Slight[1] | Moderate — retraction tuning needed; Polymaker flags stringing as a common PC problem[25] |
| Overall printing difficulty1–5 | Intermediate — dry filament and a tuned profile[22][1] | Advanced — enclosure, hardware upgrades, tuning; hardened nozzle mandatory[22][3] |
| Hardware Wear & Reliability | ||
| Nozzle hardness required1–4 | Brass fine indefinitely[22] | Hardened steel required[22] |
| Abrasiveness1–5 | Non-abrasive[22] | Highly abrasive — standard CF composite[22] |
| Nozzle clog risk1–5 | Low — no special hot-end required and clogging is not among the listed drawbacks; Prusa lists no drybox and no hardened nozzle[26][27] | High — jams from moisture, heat creep or particles; PC already absorbs water from the air and 3DXTech adds a hardened 0.4 mm minimum nozzle, 0.25 mm layers and a 120 °C pre-dry[28][23][29] |
| Heat-creep / jam sensitivity1–5 | Slightly sensitive[26] | Slightly sensitive[23] |
| Hotend requirement | No special hot-end required[26] | All-metal hot end required (Simplify3D)[23] |
| Moisture Behaviour | ||
| Moisture absorption (hygroscopicity)1–5 | Moderate — 0.65 % saturated at 25 °C / 55 % RH (Bambu Lab); Polymaker measures 0.51 % maximum uptake for ABS Pro[5][6] | Low (0.1–0.3 %) — the PC matrix takes up 0.15–0.25 % and 3DXTech specifies a 120 °C, 4 h pre-dry[30][31][28] |
| Equilibrium moisture content at ~50 % RH% | 0.65 saturated at 25 °C / 55 % RH (Bambu Lab); 0.51 maximum (Polymaker ABS Pro)[5][6] | 0.11 after 7 days at 24 °C / 22 % RH (Prusa Polymers)[3] |
| Drying temperature & time | 80 °C for 8 h (Bambu Lab); 70 °C for 6 h (Polymaker)[5][1] | Not documented |
| Symptoms when wet | Bubbling and popping at the nozzle, stringing, rough surface and weak layers[32] | Bubbling and popping at the nozzle, stringing and a rough surface[32] |
| Effect of moisture on strength | Polymaker rates ABS moderate-sensitivity and publishes no dry-versus-conditioned figures; the loss appears as poor layer adhesion and surface defects rather than a stated strength delta[32] | No dry-versus-conditioned figures are published. Polymaker calls PC highly hygroscopic and requires a 70–80 °C dry for 6–8 h; run wet, the loss shows as surface defects and poor layer adhesion[25][32] |
| Storage requirement | Sealed with desiccant; Polymaker rates ABS moderate-sensitivity and advises periodic drying in humid climates[32] | Airtight containers with desiccant to prevent reabsorption[25] |
| Mechanical Properties | ||
| Tensile strength (XY)MPa | 33 ± 3 (Bambu Lab) to 35 (Polymaker ABS Pro and Max) printed XY, ISO 527; 3DXTech quotes 42 at break[5][6][7][33] | 64 ± 3 printed horizontal and 70 ± 3 printed vertical at yield, ISO 527-1 (Prusament); 3DXTech quotes 73 at break[3][4] |
| Young's modulusMPa | 2200 ± 190 (Bambu Lab) to 2330 (Polymaker ABS Pro) printed XY, ISO 527; 3DXTech quotes 1950[5][6][33] | 2600 printed horizontal and 3200 printed vertical, ISO 527-1 (Prusament); 3DXTech quotes 6980[3][4] |
| Elongation at break% | 6.7 (ABS Max) to 10.5 (Bambu Lab) at break, printed XY, ISO 527[5][6][7] | 4.6 at yield printed horizontal (Prusament); 3DXTech quotes 2.1 at break[3][4] |
| Flexural strengthMPa | 60 (ABS Pro) to 63 (ABS Max) printed XY, ISO 178; Bambu Lab 62 ± 4; 3DXTech quotes 76[5][6][7][33] | 94 ± 3 printed horizontal and 130 ± 2 printed vertical, ISO 178 (Prusament); 3DXTech quotes 85[3][4] |
| Flexural modulusMPa | 1880 ± 110 (Bambu Lab) to 2500 (ABS Max) printed XY, ISO 178[5][7] | 3500 printed horizontal and 4200 printed vertical, ISO 178 (Prusament); 3DXTech quotes 6540[3][4] |
| Charpy impact, notchedkJ/m² | 10.5 (ABS Max) and 14.5 (ABS Pro) printed XY, ISO 179, notched; PolyLite ABS 18.0 ± 0.9 and Bambu Lab 21.5 ± 2.2[1][6][7][5] | 12 ± 1 printed horizontal and 17 ± 2 printed vertical, ISO 179-1 notched (Prusament)[3] |
| Other impact data | Charpy unnotched 39.3 ± 3.6 printed XY (Bambu Lab, ISO 179); notched 21.5 ± 2.2[5] | Charpy unnotched 32 ± 5 printed horizontal and 35 ± 4 printed vertical (Prusament, ISO 179-1)[3] |
| Layer adhesion / Z tensileMPa | 21.9 (ABS Pro) to 29.7 (PolyLite) printed Z, ISO 527; Bambu Lab 28 ± 2[5][1][6] | 23 ± 2 (Prusa Polymers interlayer adhesion test) — above the 21 ± 2 of unfilled Prusament PC Blend[3][31] |
| Brittleness1–5 | Tough — absorbs impact, yields before breaking[5][1] | Moderate[3][4] |
| Hardness (scale-specific)Shore A / Shore D / Rockwell | Not documented | 83 Shore D (Prusa Polymers method), against 79 for unfilled Prusament PC Blend[3][31] |
| Creep resistance / sustained load1–5 | Moderate — no printed-ABS creep test found; Tg of 101–126 °C keeps room-temperature service far below softening, unlike PLA[1][6][7] | Excellent — holds load for years. Room-temperature tensile creep of moulded unfilled PC ran unbroken at 41 MPa until the test was stopped; short carbon fibre raises the flexural modulus from about 2.1 to 3.5-6.5 GPa, which reduces creep strain further[34][3] |
| Fatigue / repeated-flex resistance1–5 | Moderate — no printed-ABS S-N curve found; 10.5 % elongation and 21.5 kJ/m² notched Charpy give far more cyclic tolerance than PLA[5][35] | Good. No fatigue test data was found for a carbon-fibre PC filament; the unfilled polymer is rated Good on the same scale[34] |
| Elasticity / flexibility1–5 | Rigid[5] | Rigid[3] |
| Z strength as % of XY% | 85 (Bambu Lab, printed Z against XY tensile); 63 for Polymaker ABS Pro[5][6] | Not documented |
| Thermal Properties | ||
| HDT at 0.45 MPa°C | 87 (Bambu Lab) to 118 (Polymaker ABS Max), ISO 75 at 0.45 MPa; PolyLite ABS 100[5][1][7] | 114 (ISO 75, 0.45 MPa, Prusament)[3] |
| HDT at 1.8 MPa°C | 84 (Bambu Lab) to 113 (Polymaker ABS Max), ISO 75 at 1.8 MPa; PolyLite ABS 98[5][1][7] | 106 (ISO 75, 1.8 MPa, Prusament), against 93 for unfilled Prusament PC Blend[3][31] |
| Glass transition (Tg)°C | 101 (PolyLite) to 126 (ABS Max), DSC; 105 quoted by 3DXTech[1][7][33] | 127 (3DXTech, DSC)[4] |
| Melting point / Vicat°C | Amorphous — no melting point; Vicat 104 (PolyLite) to 127 (ABS Max), ISO 306[1][7] | Not documented |
| Continuous service temperature°C | 101 measured on a loaded glass-filled ABS bar (My Tech Fun); unfilled ABS is bounded by its 84–98 °C heat deflection[36][5][1] | 113 — Prusa publishes this as the temperature resistance of Prusament PC Blend[31] |
| Annealing response | Decomposition above 380 °C (PolyLite ABS, TGA)[1] | Not documented |
| Thermal expansion (CTE)µm/m·K | 86 ± 3 at 0° and 89 ± 3 at 90° raster (printed, fibre Bragg grating, 25–50 °C); 82 for a neat large-format bead at 30 °C[37][38] | Not documented |
| Flammability / UL 94 | Flammable; no UL 94 rating published for standard ABS, though V-0 grades exist[39][5] | Not documented |
| Environment & Chemical | ||
| UV resistance1–5 | Months outdoors before embrittlement[21] | Degrades within weeks outdoors unless stabilised[25] |
| Chemical resistance | Good against weak acids, weak alkalis, oils and grease; poor against strong acids; dissolved by acetone[1] | Withstands oils, solvents and fuels; Polymaker rates it good against weak acids[25] |
| Water / humidity resistance in service1–5 | Good — minor absorption[5] | Not documented |
| Food contact | Not food safe — Polymaker cites potential chemical leaching[21] | Bisphenol-A polycarbonate is not offered as food-contact filament[25] |
| Biodegradability / compostability | Not biodegradable[21] | Not biodegradable[25] |
| Recyclability | Mechanically recyclable as resin code 9, but not accepted in household plastic collection[21] | Mechanically recyclable but not accepted in household plastic collection[25] |
| Electrical & ESD properties | Surface resistance above 10¹³ ohm/sq — insulating (3DXTech, ASTM D257)[33] | Surface resistance above 10⁹ ohm/sq — not static-dissipative (3DXTech, ASTM D257)[4] |
| Health & Safety | ||
| Fume toxicity1–5 | High — hazardous VOC such as styrene; enclosure and filtration needed[40][22] | Moderate — measurable VOCs and UFPs, ventilation advised[40] |
| VOC emission rateµg/min | 12–113 styrene, the dominant VOC from every ABS and HIPS combination tested[40] | Not documented |
| Ultrafine-particle emission rateparticles/min | 2 × 10¹⁰ to 9 × 10¹⁰ median across all ABS printers, two orders of magnitude above PLA's ≈1 × 10⁸[40] | ≈4 × 10¹⁰ median — the highest ultrafine-particle rate of the nine filaments in the chamber study, above every ABS tested[40] |
| Hazardous species emitted | Styrene dominates. Bambu Lab states ABS and ASA release harmful gases such as styrene at printing temperature, which can be toxic and cause dizziness or nausea[40][22] | Not documented |
| Ventilation / filtration requirement1–5 | Enclosure with carbon and HEPA filtration — an enclosure alone cut measured UFP by only about 35 %[40][22] | Ventilated room or enclosure recommended[40][22] |
| Dust & fibre handling hazard | Not documented | Carbon fibre is bound in the matrix; sanding dust should not be inhaled[4] |
| Post-Processing | ||
| Sanding & machining | Sands well and takes filler; the usual preparation before painting[21] | Sands and machines well; the toughness means it cuts rather than chips[23] |
| Gluing & solvent welding | Solvent-welds with acetone[1] | Cyanoacrylate; dichloromethane solvent-welds PC but is a laboratory reagent[23] |
| Vapour / chemical smoothing | Acetone vapour smoothing works — ABS dissolves in acetone[1] | No practical vapour smoothing[23] |
| Support material pairing | HIPS breaks away or dissolves in d-limonene; Bambu Lab sells a dedicated Support for ABS[41][22] | Prints its own supports; 3DXTech sells a dedicated PC break-away support[23] |
| Dimensional accuracy & detail | Warping and cooling-stress cracking are the accuracy limits, not shrinkage of the melt[22] | Not documented |
| Solvents & Solubility | ||
| Soluble in | Acetone dissolves it — the basis of ABS slurry; so do MEK, THF, ethyl acetate, chloroform, dichloromethane and toluene.[42][1] | Dichloromethane and chloroform dissolve the matrix and leave the fibre; DMF and dioxane do the same (Covestro).[43] |
| Softened or crazed by | Petrol and perchloroethylene soften it and benzene attacks it; d-limonene disrupts layer adhesion in some ABS and ASA grades.[42][44] | Methanol, butyl acetate, ether, 1 % NaOH and phthalate plasticisers stress-crack it; acetone, MEK and xylene swell it.[43] |
| Solvent welding & smoothing agent | Acetone: about 20 min of vapour at 80 °C over 5 mm of liquid. Prusa measured layer adhesion more than doubled.[45] | Dichloromethane cement welds the resin, but the fibre keeps the joint from flowing closed. Controlled carcinogen.[46] |
